3-Series (E46, E90)Chat relating to the BMW 3-Series from 1999 to Current. Models include: BMW 316i, BMW 318i, BMW 318Ci, BMW 320i, BMW 323i, BMW 325i, BMW 330i, BMW 328 Ci, BMW 328i, BMW 325i/xi, BMW 330Ci, BMW 320d, BMW 330d, BMW 335d.
Just noticed this yesterday that my A/C seemed to have a mind of its own. It would turn on anytime "it wanted" and turn off anytime. When it was really hot here.....the A/C would be off....if i turn the A/C button off and keep the blower on cold then i get cold air through the vents. The moment i turn on the A/C....boom ...no more cold air. I am thinking blower? Resistor?......anyideas and how much would that empty my wallet by? I of course mean if i take it to a shop not do it by myself.
if there is air coming out of the vents then it's not a blower problem, if the blower speed stays constant (when not in auto mode of course) then its probably not a resistor problem...Agree with stated above, what setting are u using? If you manually turn on the A/C and it blows room temp to warm air you may need to have the system recharged...I don't know what to quote you maybe someone would have a better idea or call around to get prices.
If i have the climate control on AUTO and keep the dial (between the blower vents) on extreme clod or hot.....i can feel cold/hot air come out but not really blowing hard even when the AUTO settings show the fan speed to be high. Yet cold/hot air does come out of the vents (not A/C cold but cold). Now When I turn on the A/C button everything stops.....no cold air-no hot air- nothing. Again when I turn the A/C off....cold air starts to come out of the vents but very softly and I cannot manually change the fan speed AT ALL. I have no manual control over the fan speed. So I did a search of the forums and I think this problem is pretty unique...but dont you think its the resistor? If not the blowerr then what else could be the problem?
ADDITIONALLY once in a blue moon the A/C does work (like out of the blue) and cooled well....but after a few seconds cuts out suddenly. So I doubt that it needs to be recharged.
Any ideas zibby? anybody.....i am going to the shop this week.....would love to have some ideas before i give myself to the wolves.:lol:
Well E36's do have an annoying tendency to have their climate controls die. There's a guy on ebay that fixes them, search for "e36 climate control." He'd at least be a good place to start with questions even if you don't have him repair it.
Just an update for anyone wondering on this problem.....my A/C all of sudden three days back is back to working like a breeze ("pun intended"). Like nuthing had happened. I talked to my designated mechanic and he thought that my end stage unit was about to conck off. Yet he said if its working now dont fix it....but he feels its gonna go anytime and I am keeping my fingers crossed it doesnt happen till later this year...i need the dough to upgrade my damn car. Wish me luck.....
i had a similar problem... not the exact same but i believe it was my thermostat. if i remember correctly. make sure that is working correctly before you invest in a really expensive repair... thermostat repairs are not to bad in price
